摘要

自1996年10月至1999年9月，於全島18個地點採集樹蛙卵泡(foam nest)，以瞭解台灣地區蛙蠅(frogfly)種類與分布情形。調查期間共觀察到803個翡翠樹蛙(Rhacophorus prasinatus)卵泡、50個莫氏樹蛙(R. moltrechti)卵泡、3個橙腹樹蛙(R. aurantiventris)卵泡、101個台北樹蛙(R. taipeianus)卵泡、3個諸羅樹蛙(R. arvalis)卵泡及185個白頜樹蛙(Polypedates megacephalus)卵泡。結果在全省各地的採集地中發現麗蠅科(Calliphoridae)越北絳蠅(Caiusa coomani)幼蟲普遍寄生於樹蛙卵泡上。另外在實驗室內觀察到一未知種蚤蠅(phorid)產卵於已遭越北絳蠅寄生而腐敗的卵泡上。6種樹蛙卵泡遭越北絳蠅寄生之寄生率分別為：翡翠樹蛙38%，莫氏樹蛙24%，橙腹樹蛙33%，白頜樹蛙55%，諸羅樹蛙與台北樹蛙卵泡未曾發現遭寄生。常溫下，絳蠅卵孵化約需1天，一齡蛆孵化後至化蛹約需3-5天，化蛹後至蠅羽化約需5-11天。

From October 1996 through September 1999, totals of 803 foam nests of Rhacophorus prasinatus, 50 of R. moltrechti, 3 of R. aurantiventris, 101 of R. taipeianus, 3 of R. arvalis, and 185 of Polypedates megacephalus were collected and inspected from various localities in Taiwan. One species of dipterous fly belonging to the Calliphoridae was discovered in these foam nests. The calliphorid was identified as Caiusa coomani. Larvae of C. coomani extensively infested foam nests all over the island of Taiwan. The percentages of infestation were for 38% R. prasinatus, 24% R. moltrechti, 33% R. aurantiventris, and 55% P. megacephalus. No infestation was found in foam nests of R. taipeianus or R. arvalis. It took about 1 d for eggs of C. coomani to hatch, and 3-5 d for larvae to pupate, and 5-11 d for adult flies to emerge. Maggots consumed developing frog embryos, and caused extensive death. In the laboratory, phorids oviposited in decayed foam nests infested by C. coomani. The detail distributions of frogflies are discussed in the paper.
